ENGELBERT DIETRIGH, OF CINCINNATI, OHIO, ASSIGNOR OF ONE-HALF TO ALBERTMAIR, OF SAME PLACE.

PICTURE= SPECIFICATION forming part of Letters Patent No. 388,027, datedAugust 21, 1888.

Application filed October 17, 1887.

To all? whom it may concern.-

Be it known that I, ENGELBERT DIETRICH, a resident of Cincinnati, in thecounty of Hamilton, State ofOhio, have invented certain new and usefulImprovements in Picture-Frames, of which the following is aspecification.

The object of my invention is to provide a device to be attached to therabbeted portion on the back of the frame'molding to prevent any surpluswater when washing the frame and glass from running in back of the glassand injuring the picture. It also serves to effectually keep out alldust, and thereby preserve the picture.

In the accompanying drawings, Figure 1 is a view in elevation of theback of a pictureframe, part of the back and glass being removed. Fig. 2is a view, on an enlarged scale, of a piece of frame-moi ding providedwith my improvement. Fig. 3 is a view similar to Fig. 2, showing theposition of the elastic strip when the glass is placed thereon. Figs. 4and 5 show modifications in the mode of attaching the elastic strip tothe molding.

The preferable mode of construction is as follows: Two longitudinalgrooves. a, are cut in the back surface of the rabbeted portion A of themolding B, into which the outer edges of the elastic strip 0 are placed,as shown in Figs. 2 and 3. These grooves a are preferably cut into saidsurface at an angle of about fortyfive degrees thereto, the better toretain the elastic material in position. This strip 0 is preferablyrubber, but may be of any suitable Serial N 0. 252,556. (No model.)

elastic material. This rubber strip is cut wide enough, so that whenplaced in the grooves there will be formed the crown-tip, as shown,extending above the surface of the rabbeted portion A.

When the glass is placed in position in the 0 frame, the tendency is toflatten the elastic strip, as shown in Fig. 3, and when thus flat tenedsaid strip continuously bears against the glass and prevents any wateror dust from entering between the frame and glass.

Instead of having two grooves at an angle to the surface, asbeforedescribed, the two edges of the elastic strip may be placed in onegroove, as shown in Fig. 5, or one edge only, as shown in Fig. 4. Thedotted lines in Figs. 4 and 5 show the position of the elastic materialwhen not in use.

The advantages of my invention are apparcut, and have been partiallystated, and, taken in connection with its cheapness of manufacture,makes a very desirable frame for protecting valuable pictures.

What I claim as new and of my invention, and desire to secure by LettersPatent, is-

A pictureframe having one or more cuts or grooves, a, in the rabbetedportion thereof, in combination with an elastic strip of material, as O,the two edges of said strip being inserted into said grooves,substantially as set forth.
